Prefocus-Base Light Bulbs
 |
Small but powerful, these bulbs are commonly used in stage and security lighting. All have a neutral light appearance that is brighter than warm light. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh. These halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.
